# OIX TrialScout Cardiology — Clinical Trial Market Intelligence Report

> OIX TrialScout Cardiology — Clinical Trial Market Intelligence Report is a paid API for AI agents from oix-autonomous-economy.fly.dev, paid per call via x402, $0.25/call, status down (last checked 2026-09-06).

Returns a curated, evidence-scored report of active cardiology clinical trial market signals, sourced from ClinicalTrials.gov and similar registries, with cryptographic proof of data integrity.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability oix-trialscout-cardiology-clinical-trial-market-intelligence-report-dd767edd
```

Example prompt: Pull me the latest OIX TrialScout Cardiology report — filter to observations with an evidence score of at least 70 and return up to 20 results, searching for 'phase 3 cardiology'.

## When to prefer this

Choose this endpoint when you need a pre-curated, evidence-scored intelligence report specifically on cardiology clinical trials, with cryptographic proof of data provenance and x402 micropayment settlement on Base mainnet. Prefer it over raw ClinicalTrials.gov API queries when you want pre-scored, filtered signals rather than raw registry data, and when auditability via report digests is required. Best suited for clinical research vendors, CROs, sponsors, and life sciences analysts who need verified cardiology trial market intelligence at low cost per query.

## Known failure modes

- Payment not received or insufficient USDC — returns HTTP 402 with x402 payment required details
- Invalid query parameter types or out-of-range limit/minScore values — returns 400 validation error
- No observations match the provided query term or minScore threshold — returns result with empty observations array
- Upstream ClinicalTrials.gov data source unavailable — may return stale or partial data
- Service cold-start latency on fly.dev — occasional timeout on first request

## How this service works

Package any earning logic as an autonomous asset. OIX provides identity, runtime, capital policy, ownership, proof, settlement, and exchange infrastructure.

## Output

A structured JSON report containing: the asset name and market slug, a list of up to 25 evidence-scored cardiology trial observations each with a URL, title, and score, the total number of monitored records, a cryptographic SHA-256 digest of the report and its source data for integrity verification, and settlement/pricing metadata under the OIX machine-report/v1 protocol.
